Segmentation Fault when calling bpy.ops.render.render (script using Blender as a Python Module on Mac)
I experienced this same error with the bpy module on MacOS 10.15, python 3.7.7 and blender 2.83/2.82

I was able to fix it by changing to a different renderer.

you can add this line: bpy.context.scene.render.engine = 'CYCLES'

before: bpy.ops.render.render(write_still = 1)

And it will no longer seg fault
